While not without some degree of criticism, in my experience The Enneagram is
a wonderful tool for growth and change; for working with what Jung call’s our
shadows and our pathologies for the sake of health and wholeness. If affirms
strongly the gifts and richness of difference,
while at the same time aiding in ones quest for self-awareness, consciousness
and relational health. Sadly I’ve also seen it used badly – a tool for
self-justification, blame, avoidance, and manipulation etc.

From a Spiritual Direction point of view it’s a really important too.
Really useful too in relationship-counseling and such like.
